[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figure 1 and Figure 2 This embodiment provides a lifting device (hereinafter referred to as lifting device 100) for lifting rollers inside the equipment 200 used in strip steel production, such as rolling mill rolls, tension rolls, drive rolls, and steering rolls.

[0020] The lifting device 100 in this embodiment includes a supporting component 1 and a lifting component 2 that cooperate with each other, wherein there are two supporting components 1 and two lifting components 2.

[0021] The support assembly 1 includes a fixed rod 11 for support on the device 200 and a slide rail 12 mounted on the upper end of the fixed rod 11. The extension direction of the slide rail 12 is parallel to the axial direction of the roller 300.

[0022] like Figure 1As shown, the hoisting assembly 2 includes a hoisting rod 21 and a roller sleeve 22. The hoisting rod 21 includes a horizontal part 211 and a vertical part 212 connected together. A hoisting point 24 for connecting the crane hook is provided at the connection between the horizontal part 211 and the vertical part 212. A roller sleeve 22 for fitting the roller end 301 is provided at the lower end of the vertical part 212 away from the hoisting point 24. A sliding rod 23 is provided at the end of the horizontal part 211 away from the hoisting point 24.

[0023] Two slide rods 23 are detachably mounted on their corresponding slide rails 12 and form a sliding connection. Under external force, they respectively drive two roller sleeves 22 to fit into their corresponding roller ends 301.

[0024] In this embodiment, as Figure 1 As shown, the boom 21 is L-shaped, that is, the angle between the horizontal part 211 and the vertical part 212 is 90 degrees, and a handle 25 is provided at the end of the horizontal part 211 near the slide bar 23, so that the operator can hold the handle 25 and apply force to the boom 21 to push the slide bar 23 on the two booms 21 to slide on the corresponding slide rail 12 until the two roller sleeves 22 are fitted into the corresponding roller ends 301.

[0025] Preferably, the inner diameter of the roller sleeve 22 is at least 100 mm larger than the outer diameter of the roller end 301 to ensure convenient and reliable hoisting operations.

[0026] In addition, such as Figure 2 As shown, the lifting method of using the lifting device 100 to lift the roller 300 in this embodiment includes the following steps:

[0027] Step S1: Fix the two fixing rods 11 at a distance from each other onto the device 200.

[0028] Step S2: The slide rails 12 of the support component 1 are respectively mounted on the upper ends of the two fixed rods 11 away from the device 200.

[0029] In step S3, the crane hooks are respectively attached to the lifting points 24 on the lifting rods 21 of the two lifting components 2, and slowly lowered until the sliding rods 23 on the two lifting rods 21 are respectively placed on the slide rails 12. At this time, the two lifting rods 21 and the roller sleeves 22 are located on both sides of the equipment 200.

[0030] In step S4, the operator holds the handle 25 and pushes the two lifting rods 21 along the extension direction of the two slide rails 12, so that the roller sleeves 22 on the two lifting rods 21 approach the corresponding roller ends 301, until they are fitted onto the corresponding roller ends 301. This avoids the operator entering the equipment 200 for hoisting operations. The lengths of the vertical part 212 of the lifting rod 21 and the fixed rod 11 are matched with the hoisting height of the roller 300 to ensure that the center of the roller sleeve 22 is aligned with the center of the roller end 301, thereby facilitating the quick and accurate hanging or fitting of the roller sleeve 22 onto the roller end 301.

[0031] Step S5: Then, raise the crane hook and lift the roller 300 using two lifting components 2, and move it to a preset area outside the equipment 200 for placement.

[0032] In summary, when it is necessary to hoist the rollers 300 inside the hoisting equipment 200, the slide rails 12 of the support assembly 1 and the slide rods 23 on the hoisting rods 21 of the hoisting assembly 2 work together to allow the roller sleeves 22 on the two hoisting rods 21 to be laterally fitted into the corresponding roller ends 301 on the outside of the equipment 200. This operation is simple and the safety of the operators can be guaranteed.

[0033] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
